   3 // This header defines constants and structures that are useful when parsing
   4 // DDS files.  DDS files were originally designed to use several structures
   5 // and constants that are native to DirectDraw and are defined in ddraw.h,
   6 // such as DDSURFACEDESC2 and DDSCAPS2.  This file defines similar
   7 // (compatible) constants and structures so that one can use DDS files
   8 // without needing to include ddraw.h.
